heat movement
in which direction does thermal energy always travel?
warm to cool
Why do metals feel hotter or colder than wood?
Metals are excellent Conductors. They transfer heat energy much more easily and quickly than wood does.
A group of students performed an experiment to see whether running in place for two minutes or being in a hot room would increase body temperature.
They had five students sit in a chair for two minutes and then measured their body temperature.
They had the same five students run in place for two minutes in a hot room and then measured their body temperature after running.
They repeated the experiment three times.
They analyzed their results, they concluded that running in place does increase body temperature and that being in a hot room does increase body temperature.
What was wrong with Experiment 1?
They included more than one independent variables.
A patient comes to you with complaints of pain, tingling, and numbness in her left foot. The patient has no problems with movement. Brain scans, CSF, and EMG tests were all normal.
Nerve conduction velocity tests were abnormal.
This information leads you to believe the problem is in the peripheral nervous system. Given the choices below, which structure is the most likely location of the problem?
Sensory neurons
Heat moving through fluids (liquids and gases)
Conduction
Why is the upstairs of a house usually warmer than the basement?
Because of convection, Warm air is less dense then cool air, which Causes the warm are to rise and the cool air to sink.
This microorganism causes strep throat. It can multiply without a host. It can be treated with antibiotics. It is so small, you would need to view it through a microscope at school.
What type of disease agent is this microorganism?
Bacteria
Heat moving through solids by direct contact.
Convection
Why won't a blanket make a plastic doll feel warm?
Blankets don't generate heat they only trap heat from a worm source.
What functions might be affected in a patient with a tumor in the occipital lobe?
Visual perception and some forms of visual short-term memory
You place a hot boiled egg into a bowl of cold water. Describe the energy
Energy moves from the Egg to the Water
You leave a metal plate and a plastic plate in a freezer overnight. Which one is at a lower temperature?
Neither; they're the same temperature.
A patient comes to you with complaints of intense headaches on the left side of his head just behind his eye. He also tells you that lately he has had trouble concentrating and feels unusually angry and confused. You ordered a variety of diagnostic tests and have the following results:
Patient's speech, hearing, and vision appear normal.
Patient's ability to perform memory tasks is less than expected for his age.
Patient's ability to control movement and balance appear normal.
Due to these symptoms, you suspect an issue with his central nervous system. What additional test or tests would you order to help with the diagnosis and why?
Students can recommend Brain Scans, (MRI or CT
Heat moving through electromagnetic waves like light
Radiation
You want to keep a popsicle from melting in your backpack. Based on the "Insulators" section of your guide, should you wrap it in aluminum foil or a thick wool sock?
A thick wool Sock
Lindsey is taking pictures of animals at a local park. She sees a squirrel run across the grass and up a nearby tree. Lindsey picks up her camera and takes a picture of the squirrel
Explain how the nervous system worked to sense, process, and respond to stimuli in Lindsey's scenario. In your explanation, include the input the peripheral nervous
